ABSTRACT
Geoengineering refers to a set of proposals that have been made for deliberate human intervention in the earth system to lessen the effects of Anthropogenic climate change. This chapter maps discourses in scientific and policy literatures that implicate the Antarctic region in geoengineering proposals. The chapter identifies three such discourses of enhanced reflectivity, enhanced carbon sequestration and glacial stabilisation which implicate Antarctic ice sheets, sea ice and the surrounding Southern Ocean. This chapter analyses what these geoengineering discourses mean for existing governance arrangements in the region, including the Antarctic Treaty System. In doing so, the chapter highlights that, through climate change, the Anthropocene is reshaping Antarctica in both a material and a discursive sense.
